Has anyone had a chance to look inside one of Dave Sundquist's engines to see how he did his pressurized supply filter plumbing?

I suspect the only person on the planet that knows this info is David Sundquist.

Perhaps, unless someone else is wrenching on one of his creations.

I don't think this is rocket science. The easiest and cleanest solution would be creation of a custom timing cover with built-in oil bores, attaching them to a spring-loaded filter interface.

However, looking at his crude external plumbing, I think he chose a different path.

Because of the worm drive, a separate interface between factory pump housing and timing cover will hardly be possible. Lowering the pump at the crancase by 1/4" may be possible though.
I think Dave made a special hardened steel pump housing featuring separate chambers for re-routing pressure side connections. Internal bores can be made quite small, 5-6 mm.
By changing the housing, the end plate and altering wall thickness, along with lateral pump repositioning, he may have created room for these internal bores. Connection to brake lines or similar plumbing is possible next to the upper mounting lug.
Pipes will connect to the filter interface. Preventing pipe fatigue may be a challenge when opting for this solution.

If a booster pump was conceived, as others have done, the plumbing is even simpler, but would entail changes to the timing cover.

I'm wondering why Dave Sundquist feels the need to have a go at people online?
The two that come to mind are Mikes garage
And Paul Henshaw
Very strange
